Prevalence of complex sleep apnea syndrome (ComSAS) is growing after its true characterization and clinical presentation, which enhances an appropriate diagnostic approach for its better treatment and outcome. Complex sleep apnea is a form of sleep-disordered breathing in which patients have respiratory control dysfunction and upper airway obstruction; it often clinically presents as central sleep apnea (CSA) and is mostly seen in obstructive sleep apnea (OSA) patients during the initial phase of continuous positive airway pressure (CPAP) treatment. Polysomnographic testing is a diagnostic tool required for its confirmation and the pathophysiology is characterized by the central apnea index (CAI) being five or more events/hour or the presence of disruptive Cheyne-Stokes breathing pattern. The development of complex sleep apnea involves breathing pauses, upper airway changes, variability of PaCO2 levels and an oscillating sleep state. ComSAS mainly happens in unstable sleep conditions but not necessarily always. It’s clinical presentation is difficult to distinguish from CSA and OSA because of the pattern of apneas and hypopneas where most hypopneas are obstructive with strong periodic breathing resemblance of an oscillatory pattern. Here, we are discussing a case report of ComSAS patient with no obvious risk factors receiving CPAP therapy.
